Title: Improvements in or relating to circular knitting machines, articles and fabrics made thereon and the method of knitting the same
IPC: D04B15/60
Filed: 1935-11-02
Abstract: 465,349. Knitting-machines. STIBBE & CO., Ltd., G., STIBBE, E. V., and BARSBY, E. S. Nov. 2, 1935, No. 30318. [Class 74 (ii)] In circular knitting- machines of the independent needle type and provided with yarn-changing means, including feed fingers, and means for trapping and severing the yarns as and when they are changed, yarn-severing means are arranged in close proximity to the feed fingers and are constructed and operated so as to cut a withdrawn yarn, which would normally form a float, at a point along the non-knitted portion which is close to the feed finger and to the last needle which has knitted the yarn. A movable member is adapted to be actuated at the desired time to insert the yarn in the severing-means. By these means a seamless hose or half hose is produced having an instep horizontally striped or patterned and also striped or patterned by wrap or lap threads in conjunction with a split foot, or a plain foot bottom, or a plain spliced foot bottom, without float threads. The severing means with associated yarn-trapping means 1, Fig. 1, are arranged within the latch ring on a bracket 5 bolted to a radial extension of the ring, thread fingers 3 adapted to be raised and lowered into non-feeding and feeding positions being mounted within the usual mouthpiece 2a. The arrangement is such that when a yarn is to be withdrawn, the length extending from the last needle 27<1> to knit it to the raised finger is drawn by an oscillating finger plate 21, Fig. 5, between trapping members 17, 18 and separated cutting-blades 9, 10 which. are operated to sever the yarn by mechanism so timed in relation to the travel of the needle 27<1> that the cut end is as short as possible. When the feed finger is again lowered, the yarn is pulled between the hooks of adjacent needles 27<11> and is drawn by them out of the trapping-device. The severing is effected between the edges of feet 9<a>, 10<a> projecting from the bars 9, 10, Figs. 7 and 8, which are closed by a spring 14 connected to the blade. The trapping-plate 17 and spring-pressed lever 18 are arranged in front of the bars 9, 10, and the finger-plate 21 is mounted between them. An extension 12 from the bar 10 is adapted to be engaged by an arm 13 on a rock-shaft 6, actuated, for example, from cams on the main shaft through levers 25, 26, Fig. 1, and carries a pin 23 engaging a cam slot 21b in the finger-plate 21. When a feed finger is raised the rock-shaft 6 is first operated to open the cutting device and to move the finger-plate towards the latch ring, and is then released to swing the fingerplate towards the axis of the needle cylinder, so as to insert the yarn in the trapper and the cutting-device, and to lock the trapper by a pin 21<a>. Specification 300,605, [Class 74 (ii)], is referred to.

Title: Improvements in or relating to processes and apparatus for the preparation of parboiled rice
IPC: A23L7/196
Filed: 1948-11-24
Abstract: 668,288. Treating grain. FERNANDES, March 13, 1950, No. 6278/50. Class 6(iii) 30531/48. Class 58. In a process for converting crude rice into parboiled rice, while conserving in the kernels the full vitamin contents originally present, the crude rice is first soaked by imparting thereto, while in a thinly-spread condition, a slowly progressing and rolling motion and supplying water to said kernels, at a temperature preferably between 75‹ and 95‹C so that it permeates the kernels gradually, whilst the quantity of water supplied is at most only in slight excess of the amount taken up by the kernels, whereby the minimum of vitamins are washed out of the kernels; whereafter the soaked rice is slowly conveyed in a thinly-spread condition and with a rolling motion through an open vessel supplied with steam at a uniform temperature not exceeding 100‹C, whereby the vitamins diffused in the kernels are fixed; and finally drying the parboiled rice at substantially atmospheric pressure and moderate constant temperature. As shown, the soaking, steaming and drying are carried out in three separate apparatus, each similar and comprising a horizontal rotatable drum 1 (perforated only for the drying process), having a helical conveying member 2 fixed to the wall and provided with conical nozzles 5, 6 at the ends, the former being rotatably supported by a hollow sheet metal cone 7 carrying a hopper 9. Through a perforated tube 11 extending axially through the drum water and steam may be passed for the steeping and steaming processes and hot air blown through by a fan for the drying process. In a modification (Fig. 4, not shown) of the apparatus for the soaking step, the discharge end of the drum is provided with an extension having a perforated wall and a conical nozzle end into which the conical nozzle 6 of the drum extends and is provided with a helical conveying member. A receptacle under the extension catches the draining from the soaked crude rice. In another modification, Fig. 5 (not shown), the hot steeping water from the receptacle which is provided with a steam inlet to maintain temperature is pumped back through the perforated tube 11.

Patent GB-521999-A (GB)
Title: Improvements in and relating to modulating and amplifying systems
IPC: H03F1/06
Filed: 1938-10-27
Abstract: 521,999. Valve modulating and amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 27, 1938, No. 31114. Convention date, Oct. 29, 1937. [Class 40 (v)] In order to increase the efficiency of the modulating and amplifying system of a radio transmitter the load of the power amplifier is made variable under the control of the modulation, a portion of the output power being rectified and fed back to replenish the direct current power supply to the amplifier. The power amplifier 1 is driven from an exciter stage 44 which is plate modulated by means of the audio frequency transformer 46. The anode of valve 1 is shunt fed through a choke 2 from the source of anode potential 3 and the tuned output circuit 7 is connected in series with the input end of a quarter wavelength section of network 14. The output end of the network 14 is connected to the anode 22 of the modulatorrectifier valve 23 whose cathode is connected to the positive terminal of source 3, and whose grid is fed with modulating potential. The bias and phase of the modulating voltage on the grid of valve 23 is such that when the modulation is 100 per cent. positive the valve 23 is non-conducting and the end 13 of the network 14 simulates a short circuit and the full power output of valve 1 is delivered to the aerial. At carrier level, due to the conductivity of the modulator-rectifier a resistance equal to the aerial load resistance is inserted in series with the tank circuit 7. As a result valve 1 delivers only one half its maximum power and only one half of this is fed to the aerial, the other half (one quarter of the maximum) being rectified in 23 and fed back to the anode supply. The grid drive on 1 is such that at carrier level the anode voltage swing is a maximum and the negative half cycles of modulation in the output are produced by the downward swings of the driving voltage. Further action of the modulator rectifier valve is prevented during the negative half cycles of modulation by holding the bias on that valve fixed. This may be done by making carrier conditions correspond to zero bias and by providing the audio system connected to transformer 30 with such poor regulation that the grid of valve 23 cannot be driven far positive. In a modification, Fig. 2 (not shown), the quarter wave section is not employed and the power amplifier is connected to the load over a link coupling circuit with the modulator-rectifier valve in shunt in the coupling circuit. In order to reduce overall distortion, a portion of the aerial output may be rectified and the audio frequency fed back in a negative feed back sense.
